@erbanku, would gist.github.com/erbanku/eac274bc41baf6fd100013020a8de151/dc3434b9bf206269d76ee2834bf6b7e875e935a5#file-switch-between-light-dark-mode-on-windows-11-using-ahk-L1-L19 be trivial to convert to a .reg file? I ask because I want to put it through github.com/rzander/Reg2CI/blob/2f234663e5248c58202530f429eca2b0c1af664d/README.md#reg2ps-website to replace stackoverflow.com/revisions/73734302/4.

@erbanku, thank you! Did you check that they ran merely without errors, or that they actually achieved the desired result?

Anyway, I've transformed them, if of use. This allows them to be invoked via Windows automation software (like Task Scheduler) more easily:

1. Enable-DarkModeApps.PS1

   #!/usr/bin/env -S pwsh
   If ($IsWindows) {
   	If ((Test-Path -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize') -NE $True) { New-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Force -EA SilentlyContinue };
   	New-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Name 'AppsUseLightTheme' -Value 0 -PropertyType 'DWord' -Force -EA SilentlyContinue;
   }
   

2. Enable-LightModeApps.PS1

   #!/usr/bin/env -S pwsh
   If ($IsWindows) {
   	If ((Test-Path -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize') -NE $True) { New-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Force -EA SilentlyContinue };
   	New-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Name 'AppsUseLightTheme' -Value 1 -PropertyType 'DWord' -Force -EA SilentlyContinue;
   }

3. Enable-DarkModeSystem.PS1

   #!/usr/bin/env -S pwsh
   If ($IsWindows) {
   	If ((Test-Path -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize') -NE $True) { New-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Force -EA SilentlyContinue };
   	New-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Name 'SystemUsesLightTheme' -Value 0 -PropertyType 'DWord' -Force -EA SilentlyContinue;
   }

4. Enable-LightModeSystem.PS1

   #!/usr/bin/env -S pwsh
   If ($IsWindows) {
   	If ((Test-Path -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize') -NE $True) { New-Item 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Force -EA SilentlyContinue };
   	New-ItemProperty -LiteralPath 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize' -Name 'SystemUsesLightTheme' -Value 1 -PropertyType 'DWord' -Force -EA SilentlyContinue;
   }
